Technical Field

[0001] The utility model belongs to the technical field of water conservancy irrigation, and particularly relates to an irrigation device for water conservancy projects. Background Technique

[0002] Irrigation is a technical measure to supplement the water required by crops in the land. In order to ensure the normal growth of crops and obtain high and stable yields, it is necessary to supply sufficient water to the crops. Under natural conditions, due to insufficient precipitation or uneven distribution, the water requirements of crops cannot be met. Therefore, it is necessary to artificially irrigate to make up for the deficiency of natural rainfall.

[0003] There are various irrigation methods. Generally, multiple water outlets are arranged on a relatively long pipeline, and then after water is introduced into the pipeline, water is sprayed out through multiple water outlets to achieve the purpose of irrigation. However, this method can only carry out single-point continuous water conveyance, and there will definitely be places where water cannot be fully supplemented between two water conveyance points. Content of the Utility Model

[0004] The utility model provides an irrigation device for water conservancy projects, aiming to solve the problem that the current irrigation device cannot achieve the effect of uniform irrigation.

Two first gears with the same specifications and meshing with each other are horizontally rotatably connected to the upper surface of the horizontal plate. The upper surfaces of the two first gears are fixedly connected with semi-gears that are coaxial with the two first gears respectively, have the same specifications, and have an outer diameter smaller than that of the first gears. A rotating block is vertically rotatably connected to the upper surface of the main pipe body. The top end of the rotating block is fixedly connected with a second gear that alternately meshes with the two semi-gears. The top end of the second gear is fixedly connected with a hollow spray frame. A plurality of spray holes are horizontally penetrated on the outer surface of the spray frame.

[0008] Preferably, a plurality of connecting hoses respectively corresponding to the plurality of spray frames are communicated with the outer surface of the main pipe body. The other ends of the plurality of connecting hoses are respectively fixedly connected to the outer surface of the corresponding spray frame and are communicated with the inside thereof.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] In order to make the objectives, technical solutions, and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0020] Please refer toFigures 1-3 , the present utility model provides a technical solution: an irrigation device for water conservancy projects, including a main pipe body 1 and a plurality of sprinkler mechanisms, and the plurality of sprinkler mechanisms are all arranged on the outer surface of the main pipe body 1.

[0021] The structures of the plurality of sprinkler mechanisms are the same. One of the sprinkler mechanisms includes a horizontal plate 2 fixedly connected to the outer surface of the main pipe body 1 horizontally. Two first gears 3 with the same specifications and meshing with each other are rotatably connected to the upper surface of the horizontal plate 2 horizontally. Fixedly connected to the upper surfaces of the two first gears 3 are semi-gears 4 that are coaxial with the two first gears 3 respectively, have the same specifications, and have an outer diameter smaller than that of the first gears 3. A rotating block 5 is rotatably connected to the upper surface of the main pipe body 1 vertically. Fixedly connected to the top end of the rotating block 5 is a second gear 6 that meshes with the two semi-gears 4 alternately. Fixedly connected to the top end of the second gear 6 is a hollow spray frame 7. Horizontally penetrating through the outer surface of the spray frame 7 are a plurality of spray holes 8.

[0022] The axis of the rotating shaft 10 and the axis of the first gear 3 fixedly connected thereto are on the same straight line.

[0023] In this embodiment, when the device is running, one of the first gears 3 in the plurality of sprinkler mechanisms will be driven to rotate, thereby synchronously driving the other first gear 3 to rotate in the opposite direction synchronously. The semi-gears 4 on the upper surfaces of the two first gears 3 will also rotate in the opposite direction synchronously. In this process, the two semi-gears 4 mesh with the second gear 6 alternately, which will drive the second gear 6 to rotate bidirectionally alternately. The liquid sprayed out from the spray frame 7 at the top end of the second gear 6 will be sprayed out in a fan shape, and the irrigation operation can be carried out evenly, improving the practicability of the device.

[0024] Furthermore, the outer surface of the main pipe body 1 is communicated with a plurality of connecting hoses 9 corresponding to the plurality of spray frames 7 respectively. The other ends of the plurality of connecting hoses 9 are fixedly connected to the outer surfaces of the corresponding spray frames 7 and are communicated with their interiors.

[0025] In this embodiment, after the main pipe body 1 is filled with water, it will supply water to the interiors of the plurality of spray frames 7 through the plurality of connecting hoses 9. The connecting hoses 9 can move following the rotation of the spray frames 7. And because the spray frames 7 rotate back and forth bidirectionally, the hoses will not get knotted or have other problems, ensuring persistent water supply.

[0026] Furthermore, the bottom ends of the plurality of horizontal plates 2 are rotatably connected with rotating shafts 10 vertically. The top ends of the plurality of rotating shafts 10 penetrate through the horizontal plates 2 rotatably and are fixedly connected to the bottom ends of a first gear 3. Fixedly connected to the outer surfaces of the plurality of rotating shafts 10 are multi-track belt pulleys 11. Each two adjacent multi-track belt pulleys 11 are connected by a belt in a transmission manner.

[0027] In this embodiment, each two sprinkler mechanisms are drivingly connected through a multi-track pulley 11 and a belt, ensuring that the overall structure can operate synchronously. A motor is provided on a cross plate 2 at the forefront, and a pulley is fixedly connected to its output shaft. It is drivingly connected to the multi-track pulley 11 on the second sprinkler mechanism through a belt to drive the operation of the device.

[0028] Further, multiple sprinkler mechanisms are evenly spaced along the length direction of the main pipe body 1.

[0029] In this embodiment, the multiple sprinkler mechanisms being evenly spaced along the length direction of the main pipe body 1 enables the irrigation range of the device to be more uniform.

[0030] Further, the inner diameters of the multiple spray holes 8 gradually decrease from the inside to the outside.

[0031] In this embodiment, the inner diameters of the multiple spray holes 8 gradually decreasing from the inside to the outside can cause the water to be under greater pressure when discharged from the spray holes 8, thereby spraying farther.

[0032] The working principle and usage process of the present utility model: When the device is operating, a first gear 3 in one of the multiple sprinkler mechanisms is driven to rotate, thereby synchronously driving another first gear 3 to rotate in the opposite direction synchronously. The half gears 4 on their upper surfaces will also rotate in the opposite direction synchronously. During this process, the two half gears 4 alternately mesh with the second gear 6, driving the second gear 6 to rotate bidirectionally alternately. The liquid sprayed from the spray frame 7 at the top of the second gear 6 will be sprayed out in a fan shape, enabling uniform irrigation operations and improving the practicality of the device.

[0033] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
